Harbour Island is famous for its pink sand beaches, which are found all along the east side of the island. The pink hue comes from a species of foraminifera, a microscopic organism that actually has a reddish-pink shell. Harbour Island is a popular vacation destination for Americans.

The island is accessible by airplane through North Eleuthera Airport, followed by a short water taxi ride from neighbouring North Eleuthera.
